Garbled Prompts or Voice

Problem Summary

Garbled prompts or voice

Error Message

N/A

Possible Cause

There is a PIX firewall between the gateway and Unified CVP or between gateway and Unified CM.

Recommended Action

PIX firewalls can sometimes cause issues where the prompts or voice communications become garbled. In an attempt to determine if the firewall is the issue, try to temporarily circumvent the firewall to see if that resolves the issue. If it does appear to be a firewall issue, then review PIX Firewall documentation for additional information.

Release

Release 7.0(2)

Associated CDETS #

None.

Possible Cause

Another possibility is that there is a latency issue in the network that is causing IP phone jitter or bad quality prompts.

Recommended Action

The network should be analyzed to determine if jitter conditions are present. If jitter is detected, then the IP packets are getting delayed somewhere on the network.
